Did a dumpdata of my project, then in my new test I added it to fixtures.
from django.test import TestCa开发者_JAVA技巧se
class TestGoal(TestCase):
fixtures = ['test_data.json']
def test_goal(self):
"""
Tests that 1 + 1 always equals 2.
"""
self.failUnlessEqual(1 + 1, 2)
When running the test I get:
Problem installing fixture 'XXX/fixtures/test_data.json':
DoesNotExist: XXX matching query does not exist.
But manually doing loaddata works fine does not when the db is empty.
I do a dropdb, createdb a simple syncdb the try loaddata and it fails, same error.
Any clue?

Perhaps you have some foreign key troubles. If you have a model that contains a foreign key referring to another model but the other model doesn't exist, you'll get this error.
This can happen for a couple of reasons: if you are pointing to a model in another app that you didn't include in the test_data.json dump, you'll have trouble.
Also, if foreign keys change, this can break serialization -- this is especially problematic with automatically created fields like permissions or generic relations. Django 1.2 supports natural keys, which are a way to serialize using the "natural" representation of a model as a foreign key rather than an ID which might change.
